Struct EventParameter

pub struct EventParameter {
    pub attrs: Vec<Attribute>,
    pub ty: Type,
    pub indexed: Option<indexed>,
    pub name: Option<SolIdent>,
}

An event parameter.

<ty> [indexed] [name]

Fields

attrs: Vec<Attribute>

ty: Type

indexed: Option<indexed>

name: Option<SolIdent>

Implementations

impl EventParameter

pub fn as_param(&self) -> VariableDeclaration

Convert to a parameter declaration.

pub const fn is_indexed(&self) -> bool

Returns true if the parameter is indexed.

pub const fn is_non_indexed(&self) -> bool

Returns true if the event parameter is stored in the event data section.

pub fn indexed_as_hash( &self, custom_is_value_type: impl Fn(&SolPath) -> bool, ) -> bool

Returns true if the event parameter is indexed and dynamically sized. These types are hashed, and then stored in the topics as specified in the Solidity spec.

custom_is_value_type accounts for custom value types.

Trait Implementations

impl Clone for EventParameter

fn clone(&self) -> EventParameter

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EventParameter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for EventParameter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for EventParameter

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Parse for EventParameter

fn parse(input: ParseStream<'_>) -> Result<Self>

impl PartialEq for EventParameter

fn eq(&self, other: &EventParameter) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Spanned for EventParameter

fn span(&self) -> Span

Get the span of the event parameter

fn set_span(&mut self, span: Span)

Sets the span of the event parameter.

fn with_span(self, span: Span) -> Self

where Self: Sized,

Sets the span of this owned syntax tree node if it is not empty.
